Abstract
The invention relates to a method for securely sending information and a method for securely receiving the information. The method for securely sending the information comprises the following steps that a sending end splices information which needs to send; if the information which needs to send is sensitive information, the sending end carries out XOR operation encryption processing on the sensitive information and splices the encrypted sensitive information to to-be-sent information; and the sending end sends the spliced to-be-sent information to a receiving end. The method for securely receiving the information comprises the following steps that the receiving end receives the information sent by the sending end; if the received information is the sensitive information subjected to encryption processing, the receiving end carries out XOR operation decryption processing on the received information and carries out subsequent business processing on the decrypted sensitive information. Through timely detecting whether the sent information is the sensitive information, the sensitive information is encrypted according to an appointed key and a scheduled encryption algorithm if the sent information is the sensitive information, and the adopted XOR operation encryption algorithm encrypts the sensitive information, so that secure transmission of the sensitive information is realized and security for information transmission is greatly improved.
